FREEHOLD – A Monmouth County judge denied a motion Tuesday to prevent testimony at trial about an experimental video of how a 2-year-old girl strapped in a car seat could have ended up in a creek, left to die.

Arthur Morgan III, 29, of Eatontown, is charged with killing his 2-year-old daughter, Tierra Morgan-Glover, on Nov. 21, 2011 during his visitation time with her, by leaving her strapped in a car seat that was weighed down by a car jack and ended up in a creek in Shark River Park in Wall Township. Morgan led law enforcement on a nationwide manhunt before he was apprehended in San Diego, Ca. on Nov. 29, the day after the girl's funeral.

A video was created by the Monmouth County Prosecutor's Office showing three possible ways the car seat could have ended up in the water - by throwing it off the bridge, by placing it in the water from the bank and by throwing it in the water from the bank.

The defense motioned to have testimony of the video suppressed, which Judge Anthony Mellaci Jr. denied, but clarified that Albert DeAngelis, deputy chief of detectives at the Monmouth County Prosecutor’s Office, could only speak about observations he saw during the experiment and not any inferences or conclusions.

The motion came after an Oct. 22 ruling where Judge Anthony Mellaci Jr. denied a state’s request to show the video of the experiment. DeAngelis used the same make and model car seat, same car jack and a 39-pound sand bag to show ways the baby could have entered the water, Mellaci said.

When denying the ruling, calling the video “unduly prejudicial,” Mellaci said the details of the findings of the experiment could be discussed at trial.

Tuesday’s motion comes just weeks before Morgan is expected to stand trial.

Morgan sat next to his attorney in court, dressed in a yellow jumpsuit, shackled at his wrists and ankles, and appeared attentive throughout the hearing.

In October, Mellaci also denied a defense motion requesting a change in venue because of the national media attention the case has received. Mellaci also ruled in favor of the state, allowing at trial statements Morgan made during two separate occasions to be heard at trial. Public Defender Jeff Coghlan had argued that Morgan was not mirandized each time before he spoke.

Morgan is charged with murder, endangering the welfare of a child and interference with custody.

Both Coghlan and First Assistant Prosecutor Marc LeMieux declined to comment.
